Sat-Mo-Or1 - Assembly and Commissioning Fusion Tokamaks
- Dongkeun Park (Massachusetts Institute of Technology)
- Jung Tae Lee (Seoul National University, Republic of Korea)
JT-60SA is the world’s biggest operating tokamak (R=3, a=1.2) having achieved a plasma volume of 160m$^3$ in 2023. As the first of a new generation of large fusion experimental machines, its commissioning represents a unique opportunity to gain invaluable operational experience.
The magnets form the backbone of any tokamak, and the superconducting magnet systems of JT-60SA play a critical...
ITER Central Solenoid (CS) at the heart of tokamak progresses its assembly on a platform in the ITER Assembly Hall where the six coil modules are vertically stacked and connected individually to their corresponding bus bar leads, and finally to be installed with all structural components that apply a vertical pre-compression on the completed stack. The status of manufacturing and assembly of...
The ITER Pre-Compression Ring system provides radial constraint and centripetal load to the 18 TF coils. The rings are composed of six pultruded fiberglass-reinforced composite rings with an external diameter of 5.6 m, a cross-sectional area of 95,600 mm², and a weight of 3.4 tons each. These rings are designed to operate at 4.2 K during 20 years under preload given at room temperature during...
The ITER Central Solenoid (CS) is under fabrication by the US ITER organization and its subcontractors. US ITER will supply seven modules to ITER IO, six of which will be assembled in a stack that forms the ITER Central Solenoid. All CS modules (CSM) were or will be tested at 40 kA in the Final Test facility at General Atomics.
CSM 3 testing campaign took place in 2021, and a breakdown...
